The family play an important part for the market of consumer goods. This being due down to the advertisers being in competition with one another to sell their products. It also increases competition between families to keep buying all the latest gadgets and appliances. Typically adverts target children by in which they bother their parents into buying more things and spend money on them. This is one of the ways in which Marxist say that the family serves capitalism because the family generates profit for it from such things as adverts and commercial.
They also say that capitalism exploits the labour of workers and making a profit by selling the products made from their labour for more than it costed them to produce. From a Marxist perspective the family performs ideas and beliefs that justify inequality for capitalism by trying to justify and maintain inequality. As highlighted in item 2B they say that the family ‘socialising the children into accepting hierarchy’ and inequality.
